TORONTO, July 9 (Reuters)- Toronto's main stock index snapped a three-session skid on Thursday, finishing more than 1 percent higher as a rise in commodity prices gave a boost to the resource-heavy market.

Forecast-beating results from U.S. bellwether Alcoa (AA.N: Quote, Profile, Research) helped lift market sentiment early in the day, with the upbeat mood spreading to key commodity prices such as gold and oil.

"That certainly started the market out quite strong. Their loss being less than expected was a big boost, which probably fed through to oil and other commodities too," said Michael Sprung, president of Sprung & Co Investment Counsel.
